The assembly weighs 10 lblb and has a radius of gyration kGkGk_G = 0.60 ftft about its center of mass GG. The kinetic energy of the assembly is 25 ft⋅lbft⋅lb when it is in the position shown. (Figure 1)
If it rolls counterclockwise on the surface without slipping, determine its linear momentum at this instant.
The link AC (6 kg) rotates in the vertical plane about the point B. A spring (k = 600 N/m, points C to
D) of unstretched length 225 mm is fixed to the link as shown. If the link is released from rest in the position
shown below, determine its angular velocity after it has rotated 90°. You may take the moment of inertia of the
link AC about its mass center as Igac =÷ml?.
